Theory.—Vitalized emotional energy, the "Singer's Sensation," is the true motor power of the voice.

Devices.—A study of tone-color and tone-character; the idealized tone, applied and developed by the use of words and sentiment.

The student of the voice who has studied, understood, and, to a certain extent, mastered the first three great principles of voice production—the removal of all restraint, automatic breathing, high placing, and low resonance—has certainly accomplished much. He has aroused and developed the physical and mental vitality of the singer, the vitality and energy of body and mind. This is the limit of progress or development with many, at least so far as actual tone study is concerned.

There comes a time, however, in the experience of every student of the voice, a stage of the study, when, if he expects to be an artist, he must take a step in advance, a step higher; he must place himself upon a higher plane or level; he must arouse his true inner nature, the singer's sensation, that which we have called the third power. This is done by a study of emotional, or self-expression. It is done through arousing and vitalizing the emotional energy. Vitalized emotional energy, the singer's sensation, is undoubtedly the true motor power of the artist.

At just what stage of development the consideration of this higher form of study or expression should be placed before the mind of the pupil, is a question. Singers are so different, physically, mentally, and emotionally. With some I have found it best not to consider this side of the question until they have developed a fair vocal technique. This should be the case with emotional, nervous, excitable temperaments. With hard, cold, stiff, mechanical pupils, this is often the only way in which it is possible to arouse them, in order to give them a start, without wasting weeks or months of precious time.

The development of this principle of vitalized, emotional energy, depends, as a rule, upon freedom of voice and the true conditions of tone as before described. Therefore, in order to study this great question, in order to fully develop this higher form of expression, the singer must have mastered the flexible, vitalized movements given in this work, must have acquired through these movements absolute freedom of tone. Experience teaches us, however, that there are those who, while they learn, in a certain way, to do the movements comparatively well, yet do not entirely let go,—they do not free the voice. With such the study of tone color, and especially the study of soft color, not soft tone necessarily, but soft, emotional tone color, is their only salvation. It releases and relaxes all the rigid local tendencies.

There is a stage of study, as we have said, in the experience of all students of the voice, when, in order to become artists, Nature demands of them more than mere sound. There comes a time when every tone of the voice must mean something, must express something, through the character of the tone, the idealized tone. In this way the personal magnetism of the singer is imparted, heard, and felt. This means the expression of thought and feeling through the color and character of the tone, the highest known form of expression. This principle is the greatest known agency for the development of all the powers of the singer, not only the emotional and mental powers, but the physical as well. The student of the voice who studies or who is trained in this way, develops, not only in character and beauty of tone, but in actual physical power and control. This study of tone color and tone character develops new power in every way. "The mechanical and mental alone are but half development, but this is full and complete development of the entire being." In proof of this, sing a light, bright, happy thought or tone, using the clear timbre, about the middle of the voice. It will require but little strength. Then sing a more emotional thought, sentence, or tone; express deeper feeling, and it will be found that more strength is required. Again, give utterance to tone or words which express sadness, sorrow, or intense pleading, using the somber timbre of the voice, and much more strength will be required. This will be especially noticeable in the action or energy of the diaphragm and abdominal muscles. It will be found that the low muscles of the body exert more strength on somber timbre than on clear tone. This, in order to induce the deep, low setting of the voice at the organ of sound, necessary for the production of somber or dark tone, and the expression of deep, emotional feeling. It is easy to see that this means greater physical as well as emotional development; physical development, not only of every muscle of the body, but of the organ of sound itself; a development which can be attained through the study of tone color and emotional expression only.

The power of vitalized emotional energy, I might say the power of the emotional power, cannot be overestimated. The power of an emotional climax, imparted through the soft color of the voice, is often greater than that of the dramatic climax; it will often influence and affect an audience in the most startling way. We find that thought and will control all physical action in singing. If the thought is right, the action will be right; if wrong, the action will surely be wrong. When right thought and action have developed absolute freedom, then the emotional energy, the singer's sensation, the true power of the voice, should dominate everything. The mind or will controls the body through thought, but the thought must be aroused through feeling or emotion; and the feeling or emotion is inspired by the sentiment to be expressed. This means, of course, the higher form of expression, means the power of tone color and tone character; but it depends first upon all true conditions of tone, mental and physical, and then upon the temperament, upon the heart, and soul of the singer.

Singing, as we have said, is more psychological than physiological. This whole system of flexible, vitalized movements, is first aroused by right thought, and finally applied and controlled through the mind or will, in response to feeling or emotional impulse. In this way we are able to arouse and use at will the persuasive, the impressive, the fervent voice; the voice that is something more than mere sound; the voice that has character and magnetism.

Compare two voices that are equal in every way in regard to power of tone, compass, and control. The one varies the color and character of the tone continually with the change of thought and sentiment, and is enabled thereby not only to avoid monotony, but to use the impressive, persuasive voice, the tone the sentiment demands. In this way he has magnetic power and influence over an audience. The other voice may be bright, free, and clear, yet may use the same quality or color of tone constantly on all styles of singing, and on all degrees of power, it matters not what the thought or sentiment may be; and this style of voice is by no means uncommon, even among many of our public singers. Now consider the difference in the commercial value of these two voices, which should bear at least some relation to their artistic value. No artist can be truly great or fully developed without the power of vitalized, emotional energy, and variety of tone color and character.
